Subjectbug ?
First: my english is realy bad - sorry

My PC hangs sporadicaly (every 2 weeks) after heavy Network traffic.
I tried to work around the problem by changing the NIC (dmfe >
realtek, using new driver 8139too), but it din't help.
Today i had the luck ( :-( ) that the syslog-console was activ, so
that I could get the messages (otherwise the PC hangs completly, and
its no more longer possible to change the console)
The PC akts as a small server.
Main running services:
Kernel-NFS
Samba 2.2.1
mysql
sshd: OpenSSH_2.9.9p2, SSH protocols 1.5/2.0, OpenSSL 0x0090602f
apache w/ php
ip-filter

teh error ocured while i was doing a backup via ssh & tar + gzip
( something like:
ssh 192.168.0.1 tar -cSp --numeric-owner -f - /xport/netdata | gzip> \
/var/backup/hdd4/filename.tgz)
but as I said simillar errors ocure not only while running ssh.
Same error i had with earlier Kernelversions (2.4.9, 2.4.8), thats wy
i use a out-of-the-box-kernel of a Distribution (SuSE).
If this error seems to result out of a hardware error, a reply would
be verry nice.
I send you the output of dmesg as a txtfile.
I'w downloaded today aktual Kernel and try it with 2.4.17.

Thank you all for doing such a good work on this nice OS.
I work since 3 years with Linux - and I enjoi it every day.

A happy new year from Berlin
Klaus
